Low-lying levels ofTc98

The levels of ${}_{}{}^{98}{}_{}{}^{}\mathrm{Tc}$ have been investigated through the ${}_{}{}^{98}{}_{}{}^{}\mathrm{Mo}(p,n\gamma ){}_{}{}^{98}{}_{}{}^{}\mathrm{Tc}$ reaction with detection of the $\gamma$ rays. Excitation functions and $\gamma -\gamma$ coincidence spectra were used in determining the energies of the levels. A pulsed beam was used in obtaining the spectrum of the delayed radiation from the 14.6-μsec isomeric level. Thirty-four $\gamma$ rays have been assigned to twenty-three excited levels of ${}_{}{}^{98}{}_{}{}^{}\mathrm{Tc}$.
